TS EN 60276

TS EN 60276 is a terminology and nomenclature document for carbon brushes, brush-holders, commutators and slip-rings. Its subject is the naming and classification of the parts used in electrical rotating machines that transfer current between stationary and rotating elements, rather than the detailed design or performance of those parts. This listing is a withdrawn standard, and the explanation below is based on the technical topic indicated by the title.

Why these components are grouped together

Carbon brushes, brush-holders, commutators and slip-rings belong to the same current-collection system. In general technical use, a carbon brush provides the electrical contact, the brush-holder positions and supports it mechanically, and the commutator or slip-ring provides the rotating contact surface. The distinction matters because commutators are typically associated with commutation in DC machines, while slip-rings generally describe a continuous annular contact surface used for current transfer without segmented commutation.

What a nomenclature standard contributes

A terminology standard helps manufacturers, maintenance teams, engineers and technical writers use the same words for the same parts. That improves clarity in catalogues, maintenance manuals, procurement documents and training material, especially for motors, generators and related rotating electrical equipment. As a general reference, it supports consistent communication about brush types, holder arrangements and contact surfaces; it is not, by itself, a performance test standard or an operating manual.

• Carbon brushes: conductive contact elements that transfer current to or from a moving surface
• Brush-holders: mechanical supports that locate the brush and maintain contact pressure
• Commutators: rotating contact surfaces associated with commutation
• Slip-rings: ring-shaped conductive surfaces used for sliding electrical contact
